San Diego County
El Cajon anchors San Diego's East County region, and the city's older downtown core, developed decades before the surrounding hillside communities, shares San Diego County's characteristically hard imported water supply.
The Larkin Family, who lives in Bostonia, El Cajon, reached out after noticing a damp patch on the wall that never fully dried out. El Cajon's older downtown core has plumbing considerably older than the surrounding hillside communities, and shares San Diego County's hard imported water supply. What looked like it might mean tearing out a whole room turned into a same-day, targeted fix once the exact spot was confirmed.

“Our water bill jumped for two months straight and we couldn't find why. Turned out it was a slow leak behind the water heater. Professional, on time, and explained everything on the spot.”
“Salt air had corroded a fitting outside near the meter box. They traced it with the acoustic equipment without digging up my whole side yard first. Appreciated the straightforward report.”
“Good experience overall, technician was knowledgeable and thorough. Took a little longer than expected but they were clearly being careful about pinpointing the exact spot before marking it.”
“Old Victorian with plaster walls everywhere, so I was dreading this. They used thermal imaging and found the leak behind one wall panel instead of opening up the whole room. Saved us a big repair bill.”
“Ground near our garage had been soft for a while. Turned out to be the main line. They marked the exact dig spot and our plumber only had to open a two-foot section instead of the whole path.”
